Avoid background noise. Whether you have music playing in your office, or you’re sitting in a coffee shop, background noise can make it difficult for your customers to understand your greeting. Limit the noise around you when you leave your voicemail greeting.
A professional voicemail greeting is a recorded message that plays when you miss a phone call. The purpose of this recording is to inform your caller that you cannot make it to the phone, and they should leave a message. Whoever is calling you hears this message, making it important to be polite and professional.

Users often don’t invest enough time into their messages, resulting in incomplete, unprofessional, or otherwise under-whelming greetings. Sure, crafting a greeting doesn’t sound all that complicated; however, there are a number of pitfalls users can fall into—i.e. informality, terseness, sincerity, lack of direction, and more. While none of these sound too catastrophic, they are often interrelated. As such, they tend to worsen any problem. For example, humor can cause informality, worsen ambiguity, and weaken sincerity. That being said, users should strive to avoid ALL these pitfalls.
The voicemail message can be anywhere between 10- 25 seconds. Keep it as short as you can because the prospects need to hear the vital details in it.
